[0002] The dust removal bag can be regarded as the heart of the bag filter, generally called the dust removal bag or the dust filter bag. The dust removal bag is a key part during the operation of the bag filter. Usually, the cylindrical filter bag is vertically suspended in the dust collector. The fabric and design of the dust removal bag should strive for efficient filtration, easy dust stripping and long service life. The selection of the dust removal bag is crucial, which directly affects the dust removal effect of the dust collector. The dust removal bag is selected from the following aspects: factors such as the temperature, humidity and chemical properties of the gas, particle size, dust concentration, filtration velocity, and dust cleaning method.

[0003] However, the existing bag filters do not have a blowpipe that can extend into the bag. Traditional bag filters often set the blowpipe at the top of the bag and blow air into the bag, resulting in the weakening of the blowing force at the bottom of the bag, the weakening of the cleaning effect, and the reduction of the service life of the bag. Therefore, there is an urgent need for a bag dust removal induced draft fan for pesticide production to solve the above problems. Content of the Utility Model

[0004] In order to overcome the above technical problems, the purpose of the utility model is to provide a bag dust removal induced draft fan for pesticide production to solve the problems in the above background technique that the existing bag filters do not have a blowpipe that can extend into the bag, and traditional bag filters often set the blowpipe at the top of the bag and blow air into the bag, resulting in the weakening of the blowing force at the bottom of the bag, the weakening of the cleaning effect, and the reduction of the service life of the bag.

[0029] Working principle:

[0030] During use, waste gas generated in pesticide production is introduced into the housing 1 through the air inlet pipe 13. The waste gas flows to the lower part of the cloth bag 21 through the diversion plate 22. The induced draft fan 15 is turned on, so that the induced draft fan 15 evacuates the inside of the housing 1 through the air outlet pipe 14. The waste gas moves from the outside of the cloth bag 21 to the inside of the cloth bag 21, and the waste gas is filtered by the cloth bag 21. The filtered waste gas is discharged through the air outlet pipe 14 and the induced draft fan 15. The induced draft fan 15 can create a negative pressure inside the housing 1, which is convenient for guiding the flow of the waste gas and preventing the waste gas from flowing back. After long-term use, a large amount of dust will adhere to the cloth bag 21. A solenoid valve and a pulse valve are installed at the connection between the air bag 3 and the connecting hose 32. The solenoid valve and the pulse valve are opened, so that the compressed gas in the air bag 3 moves into the connecting pipe 44 through the connecting hose 32. The compressed gas in the connecting pipe 44 is ejected through the blowing pipe 45. The blowing pipe 45 blows out to the left and right sides through the first air outlet pipes 46, blows downward through the second air outlet pipes 47, and blows downward through the third air outlet pipe 48, so that the dust attached to the cloth bag falls off. The cloth bag can be cleaned comprehensively through the first air outlet pipes 46, the second air outlet pipes 47 and the third air outlet pipe 48. The lifting of the blowing pipe 45 can be realized through the lifting structure 4, which is convenient for the blowing pipe 45 to clean the cloth bag comprehensively, improves the cleaning effect, and prolongs the service life of the cloth bag.
